Degenerative changes: Degenerative changes in the cervical spine cause the vertebral body to form bone spurs. The bone spurs then encroach into the spinal canal. The first thing to happen next is the the structure around the spinal cord is displaced or compress by the spurs. In this case the dural sac that surrounds the spinal cord.
